No response on phone from vodacom

In November my IPhone stopped working so I took it for repairs at Vodacom customer care menlyn, a day later I received a message to say that my phone was ready. when I got there they said that the problem with my phone was the software and I had to pay R250 for that. Three days after receiving my phone the same problem occurred again and my phone had to be re - booked for repairs. I waited, and had not heard anything about my phone for a week and half so I decided to call them and they told me that the phone was at the repairers and it would cost close to R3000 to repair it however I told them that my phone was insured and I had completed the insurance forms the day I brought it in. They did not have the forms so I completed them again. 3 days later Vodacom insurance called me saying that I would get a refurbished phone. on Monday of 7 December 2015 I received an sms saying my fone was ready, so I decided to fetch it on the Tuesday however when I got there they said there was no phone so I decided to call them again on the Wednesday and they said the phone was ready when I got there it was not ready and I had to rebook it again. I haven't heard anything and its over a month
